IMPROVEMENT IN CONDENSE RS.

Specification forming part of Letters Patent No. 167,642, dated September 14, 1875; application file d October 7, 1874.

To all whom it may concern:

Be it known that I, HENRY W. BULKLEY, of the city of New York, in the county and State of New York, have invented certain Improvements in Steam-Condensers, of which the the following is a specification:

Myinvention relates to that class of steamcondensers which are elevated at least thirtyof eonoidal nozzles, joined'by the contracted neck E. These nozzles should be parabolic in shape to allow an easy flow of the water. B

is the exhaust-nozzle with an opening equal to the exhaust-pipe H from the engine, but contracted at the end, so as to increase the velocity of the discharge. H is the exhaustpipe from the engine M, with which it is connected by a return bend and pipe, as shown in Fig. 3. Ois the injection-pipe opening into the hollow ring K, and conveying water to the annular space between the condenser A and nozzle B. D is the delivery-pipe, at least thirtythree feet long, opening into the hot-well 0, shown in Fig. 3. P is the overflow from the hot-well. The direction of the steam and water currents is shown by the arrows. The a11- nular water-space around the end of the exhaust-nozzle B, m'ust be proportioned tothe amount of water required for condensation, so that the latter may enter in a uniform film around the exhaust steam. The dischargeneck E must also be so shaped as, to be entirely filled by the outgoing water, air, and vapor, and thus prevent all return of the latter from below.

A flow of water being supplied through pipe 0 by a natural or artificial head, (or from a pump,) and the engine started, the exhaust steam is instantly condensed, forming a par-' tial vacuum, into which the following exhaust steam rushes with greatly-increased velocity,

denser, and thereby damaging the engine, a,

common fault with ordinary jet-condensers.

' Should the supply of condensing-water fail, the engine will then exhaust, without stopping, through the condenser, into the hot-well against the pressure of the atmosphere.

The discharge-waterfrom the hot-well may be used to feed the boiler, or may be led away for any other purpose required.

My invention maybe used in connection with a vacuum-pan, steam-pump, or any other steam apparatus requlring avacuum.

I desire to disclaim using a jet of steam to exhaust the condenser, as in Absterdams patent, or streams of water forced intermittently or continuously into the condenser, to overcome by their momentum in entering the vacuum, the pressure of the atmosphere, as in Houpts and other ejector-condensers, nor do I employ the back pressure of the exhaust steam with or without valves. I also disclaim extracting the air and water from the condenser solely by a discharge-pipe thirty-three feet, or more, in height; but

I claim as my invention The conical or paraboloidal nozzles and straight connecting neck, as described, in combination with a annular water-opening, when the action is independent of any valve or valves, steam-jets, or streams of water under pressure, but is efi'ected solely by a descending column of discharge water, sufficiently high to overcome the pressureof the'atmosphere, the whole arranged substantially as de-' scribed.
